An art gallery has 18 paintings and 4 photographs displayed in equal rows on a wall,with the same number of each type of art in each row.which of the following could be the number of rows?A 2 rows, B 3 rows, C 4 rows, D 6 rows

Answers

The question is asking us to determine the number of rows in which 18 paintings and 4 photographs could be displayed, such that there should be the same number of each type of art in each row. First we have to find the GCF ( the Greatest Common Factor ) of 18 and 4. 18 = 2 * 3 * 3 and 4 = 2 * 2. The prime factors of 18 are 2 and 3 and the prime factor of 4 is 2. Therefore GCF ( 18, 4 ) = 2. There could be 2 rows, with 9 paintings and 2 photographs in each. Answer: A . 2 rows.

What radius of a circle is required to inscribe a square with an apothem of 3.536 inches?

Answers

Answer:

The radius of the circle required is 5 inches

Step-by-step explanation:

we know that

The diagonal of the square is the diameter of the circle

The length side of the square is half the apothem

Let

a ----> the apothem

r ---> the radius of the circle (half the diagonal of the square)

Applying the Pythagorean Theorem

$r^2=a^2+a^2$

we have

$a=3.536\ in$

substitute

$r^2=3.536^2+3.536^2$

$r^2=25\nr=5\ in$

Answer: C) 5 in

Sequences and equations:Position = 10, 11, 12, 13, 14
Value of term = 28, 31, 34, 37

Answers

Sequences
Sequence: a function whose domain is a set of consecutive integers.
Domain: the position of the term (1st, 2nd, 3rd, and so on).
Range: the terms of the sequence.
Terms: the numbers in the sequence.
Finite Sequence: a sequence that has a last term.
Infinite Sequence: a sequence that continues without stopping.
Rule for the nth term: means to write an equation of the arithmetic sequence.
Look at the following sequences:
an = 2, 4, 6, 8 an = 2, 4, 6, 8, …..
If n represents the position of the term, then a2 refers to the 2nd term.
Writing Terms of Sequences
To write the first six terms of a sequence, plug the numbers 1 – 6 in for n.
Example 1: Write the first six terms of the sequence.
a) an = 5 – n b) f(n) = 5n
Example 2: Write the next term in the sequence.
a) 1, 4, 9, 16, 25, ______, … b) 5, 25, 125, ______, … c) 456 , , , _____,...
789
d) 0, 3, 8, 15, 24, ______, … e) 1, 2, 5, 10, 17, ______, …
